SPlNDLE-DRIVING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 567,064, datedSeptember 1, 1896. Application filed October 12, 1895. Serial No.565,471. (No model.)

To all whom it may concern.-

Be it known that I, EUGENE ATWOOD, of Stonington, in the county of NewLondon and State of Connecticut, have invented a new and usefulImprovement in Spindle-Driving Mechanism, of which the followingis aspecification.

The object of my invention is to drive a plurality of rows of spindlesupon the opposite sides of the frame by means of a single drivingmechanism.

In the accompanying drawings I have shown a double row of spindles uponeach side of the machine-frame, the four rows being driven by two beltsengaged by belt-driving pulleys on the head-shaft of the machine.

A practical embodiment of my invention is represented in theaccompanying drawings, in which- Figure 1 is a top plan view of thedouble spindle-driving mechanism, so much of the frame being shown as isnecessary for a clear understanding of the operation of the parts. Fig.2 is aside View of the same; and Fig. 3 is a section on the line was ofFig. 2, looking toward the front of the machine.

The frame consists of suitable end uprights A A, connected by suitablecross-plates B B, which cross-plates form supports for the spindles andtheir supporting-boxes.

The spindles are denoted by O and are mounted in boxes 0, in which arelocated the bearings for the spindles O. Two rows of spindles O aremounted upon each of the plates B 13 upon opposite sides of the machine,the two rows upon each of the plates being spaced a short distanceapart. The spindles O are supported upon the plates B and B by suitablespring-actuated brackets c, which brackets yieldingly hold the doublerow of spindles upon each of the plates at the limits of theirinwardly-swinging movements toward each other.

The vertical head-shaft D is mounted at the front of the machine insuitable fixed bearings, the lower one of which d is shown, and upon thesaid head-shaft is secured a suitable drive-pulley 62, whereby the shaftD is driven from a source of power. (Not shown.) There are also securedto rotate with the head shaft D a pair of belt-driving pulleys d 61 Aspindle-driving belt E extends around one of the belt-driving pulleys dd in the present instance the pulley d and from thence extends alongbetween the double row of spindles upon the plate B and around a loosepulley F, mounted in a suitable moving support f at the rear of themachine. This pulley F is forced away from the head-shaft D fortightening the belt E by suitable spring mechanism, which mechanism inthe present instance consists'of a two-armed lever f, the upper armof-which engages the sliding support f of the pulley F and thelower'armof which is engaged by a spring f, the opposite end of which spring issecured to a suitable bracket f on the upright A of the frame.

The belt E after passing around the belt drivepulley d passes partiallyaround an idlerpulley G, located in close proximity tolthe pulleys d 61so as to direct the belt E along between the two rows of spindles uponthe plate B. The spindles G are held against the face of the belt E bythe spring-actuated brackets a, so that as the belt E is driven thespindles are rotated by frictional engagement with the belt.

The belt for driving the double row of spindles upon the opposite sideof the machine is designated by E, and it passes around the drive-pulleyd and from thence along between the two rows of spindles to a stretchingidler-pulley F, which holds the belt E taut in a manner similar to thatin which the idler-pulley F holds the belt E taut. The inner portion ofthe belt E, just after it leaves the belt-driving pulley d passespartially around the idler-pulley G, before mentioned, for directing thebelt E between the double row of spindles upon the plate B. p

The double row of spindles upon one side of the machine is located in aplane above the double row of spindles upon the opposite side of themachine, so as to allow the belts E and E to run exactly horizontallyand at the same time properly engage the two double rows of spindles toproduce the best results, and also doing away with the necessity offorming the spindles upon one side of the machine of different lengthfrom those upon the opposite side of the machine. For still furtherholding the belts E E in contact with all of the spindles I locate atdifferent distances between the double rows of spindles Ice 2 to /306aspacing idler-pulleys II. The pulleys H, F, and F are provided withsuitable flanges h, f, and f respectively, for supporting the belts E Ein their proper planes.

The mechanism as above described enables me to double the capacity of aspinner-machine and at the same time utilize only a single head-shaft.

It is evident that slight changes might be resorted to in the form andarrangement of the several parts without departing from the spirit andscope of my invention. llenee I do not wish to limit myself strictly tothe structure herein set forth; but

hat I claim is- 1. In combination, a suitable frame, two rows ofspindles upon each side of the frame, the spindles upon opposite sidesof the frame being in different planes, a vertical headshaft, means foroperating it, a pair of beltdriving pulleys on said shaft, and a pair ofhorizontallymoving belts driven by said pulleys for operating thespindles, each belt being located in a plane corresponding to the planeof the two rows of spindles which it operates, substantially as setforth.

2. In combination, a frame, two rows of spindles upon each side of theframe, a Vereach of said belts extending between the two rows ofspindles and idler-pulleys for supporting the belts in their horizontalposition and also holding them in engagement with the spindles,substantially as set forth.

3. In combination, a suitable frame, two rows of spindles upon each sideof the frame,a vertical head-shaft and means for driving it,a pair ofbelt-drivin g pulleys on said shaft, spindle-driving belts driven bysaid pulleys, an idler-pulley located between the rows of spindles uponopposite sides of the frame for directing the inner portions of each ofthe belts between the two rows of'spindles which it operates, anidler-pulley for each belt at the opposite end of the frame from theheadshaft, and idlers located between the rows of spindles for holdingthe belts in engagement with the inner sides of the spindles,substantially as set forth.

EUGENE ATWOOD.
